The crash happened on the B1091 at Yaxley near Peterborough at around 11am on January 3 this year after what prosecutor Jonathon Polnay described as "an exceptionally prolonged course of dangerous driving".

Frost's BMW X5 hit speeds of up to 117mph, used lay-bys and the hard shoulder to undertake vehicles at speed and overtook while driving into oncoming traffic, the court heard.

One witness described it as "driving like a nutter", Mr Polnay said, and on a 999 call played to the court, another witness said "if he doesn't run into someone or kill someone it will be a miracle".

Pedestrians Mr Fletcher and Mr Northam were walking facing traffic, but Frost drove along the verge on the wrong side of the road and struck them from behind.

Frost has been sentenced to 10 years and nine months for the dangerous driving offences, 16 months for money laundering and six months for assault, to run concurrently.

He will only be eligible for parole after serving two thirds of the 10-year sentence.

He had been due to be sentenced in December, but the case was called off to allow further psychiatric reports to be prepared examining Frost's state of mind at the time.

Judge praises the victims’ families for their dignified behaviour

Judge Farrell will instruct the High Sheriff to authorise a reward of £500 to Stefan Mills for his courage and sense of public duty, by pursuing a dangerous criminal.

Farrell pays tribute to the dignity with which the victims’ families have conducted themselves, and expressed his sympathy for their loss.

15:04

Driving ban

Disqualified from driving for five years, plus extension period of five years and seven months. Total driving ban of 11 years and seven months. Will be required to take an extended test before being allowed back onto the roads.

Also a restraining order against the assault victim.

15:03

Sentencing

Frost is sentenced to 10 years and nine months for dangerous driving, 16 months for money laundering, and six months for assault, to run concurrently.

He will only be up for parole after serving two thirds of the 10-year sentence.

15:00

'Nothing I can do can turn the clocks back'

Judge Farrell says he will impose concurrent sentences for the common assault charges.

“Nothing I can do can turn the clocks back or reflect the loss of human life caused by your appalling driving.”

14:59

Credit for guilty plea

Credit for guilty plea will be limited to 20 per cent.

14:51

'I have no doubt that you are dangerous'

“I have no doubt that you are dangerous.

“It is the nature of your continued, persistent association with drugs, and your dangerous behaviours when intoxicated with drugs, you will, in my judgement, become less risk averse, and more likely to take drugs.”

14:48

No reduced sentence

Judge Farrell says he will not reduce the sentence because of Frost’s mental illness.

14:47

Delusions not connected to the dangerous driving

“Frost was suffering psychiatric issues, involved with paranoid delusions. But there does not seem to be a link between his paranoid thinking and his offences.

“There appears to be no evidence his dangerous driving arose from his delusions.”

14:45

'A more overwhelming case of death by dangerous driving is hard to imagine'

“A more overwhelming case of death by dangerous driving is hard to imagine. Any talk of medical or mechanical failures is fanciful.”

14:42

More than one person was killed

“The aggravating factors are more than one person was killed as a result of the offence.

“It was a prolonged case of bad driving.

“You had consumed drugs, the victims were vulnerable road users, and you had prior convictions for dangerous driving.”

14:40

No vehicle defects

“A collision investigation report ruled out it being caused by any defect in your vehicle.”

14:40

Frost denied being the driver

“You were eventually arrested the following day, having managed to escape at Essex. Having been arrested you continued to deny having been the driver.”

14:39

'You left them there to die'

Two victims were walking along the road, facing oncoming traffic.

“You drove down the wrong side of the road, mowing them down. You left them there to die.

“Your car was damaged, and it was only that that made you stop.”

14:38

Frost assaulted a woman, judge says

Frost stopped at a service station, where he assaulted a woman. Then drove off towards Peterborough, again speeding through a housing estate, with a 30mph limit.

14:37

Driver knew what he was doing despite his mental state, judge says

“You were seen undertaking, crossing double white lines, forcing people to take evasive action.

“At one point a police car was seen by you, and you began driving normally. The fact you drove in a proper way when there was a police officer in sight showed you knew exactly what you were doing, despite your mental state, and despite your consumption of drugs.”

14:36

Cameras prove the driver was going way over the speed limit

Average speed cameras recorded a speed of 117mph, in a 60mph speed limit.

14:35

Witness said it'd be a miracle if the driver didn't kill somebody

“A member of the public saw the driving, and called police, saying: “If you didn’t kill somebody it would be a miracle. Sadly that proved to be correct.”

14:34

Judge says driver took cocaine while driving

“On the day before the incident you set off from Essex to Stansted Airport, and then on to Colchester, where you took cocaine and amphetamines.

“In the early hours of January 3 you drove to Grimsby, then having had no sleep, you drove to Grimsby, having taken cocaine. Indeed, you were doing so while driving.”

14:32

'You had deliberately consumed illicit drugs'

“There is no doubt in my mind that your behaviour on Jan 3 encompassed the most appalling, flagrant.

“With not a care to the danger it can cause to other road users, including pedestrians.

“You had deliberately consumed illicit drugs, causing significant impairment, which was all aggravated by your possession of criminal property, and your attempts to escape from the scene.”

14:31

Judge Farrell lists previous convictions

“On 24th November of this year having been declared fit to plea, you pleaded guilty to the five counts on this indictment, including two counts of causing death by dangerous driving.

“You are 39 years of age, and have previous convictions, including relevant convictions relating to dangerous driving, namely driving over the alcohol limit, and failing to stop after an accident, and driving without due care and attention.

“You also have prior criminal convictions relating to your possession of stolen property.”

14:24

Another hearing to take place in June

Judge Farrell confirms a further proceeds of crime hearing will take place on June 8, and Frost will be required to attend. This will discuss what happens to the money Frost was in possession of at the time of the crash.

14:18

Judge Farrell returns

We’re back, and Judge Farrell has returned.

12:50

Adjournment until 2.05pm

We are now having an adjournment for Judge Farrell to consider the evidence.

The sentencing will resume at 2.05pm.

12:48

"He is extremely sorry"

“He is extremely sorry about the pain and suffering this offending has caused to the families.

“It is very difficult to put into words but the mothers of those young men did so in their victim impact statements, and Mr Frost has heard those.

“In the time that he has become better he has begin to absorb the enormity of his actions. I don’t know if there is anything more I can say than that, and I don’t know if he can ever completely understand the impact these offences will have on the families.”

12:38

The defence begins the mitigation

The defence is beginning the mitigation.

It is suggested Frost made his guilty plea at the earliest possible opportunity, saving the victims’ families from testifying in court, and going through the stress of a trial.

The defence solicitor says this should be taken into account, and Frost should receive the full one-third reduction he would have received if he pleaded guilty immediately at his first court appearance.

12:30

Second psychiatrist has nothing further to add

The second psychiatrist, Dr Baird, is now in the witness stand, being given his chance to speak to Judge Farrell.

He has nothing further to add.

12:23

Frost was 'unfit to stand trial' at first court appearance

“When he first appeared before the court on the sixth of January I think it was reasonable to see him as unfit to stand trial.

“But there is no reason why he could not have given an indication of his early guilty plea.”

12:19

Prosecution psychiatrist giving evidence

The prosecution’s psychiatrist is now giving evidence.

He is Dr Smith, a consultant forensic psychiatrist.

He is being asked about Frost’s fitness to plead at an early stage, when he was first arrested last year.

12:09

'The intoxication was the active factor'

We’re now hearing a summary of those medical reports.

“The effect or impact of Mr Frost’s condition wouldn’t have been a state of untreatment.

“It would have the capacity to make Mr Frost more risk averse and more likely to poor decision making, such as driving erratically and taking drugs.

“However it wasn’t the cause. The intoxication overwhelmed the illness, and was the active factor at the time the offence was committed.”

12:04

Psychiatric doctors in court

On December 20 there was a psychiatric report produced, followed by a second full report by a different doctor. Both doctors are present here in court.
